To all whom 4ivf-may concern.' f. A Be .it known that I, WiLLiAM il. PARKns, a citizen of the United States, residing in Brooklyn, county oi' Kings, and State of New York, have invented a new and useful Improvement in Embroiderv or Ornamental Stitch Sewing-Machines, ot which the follow.- ing is a description.

This invention relates to sewingmachines, i0 and especially to the class known as em- `broidery or ornamental stitch. machines.

June 26, 1.900, and February i8, 1902,

Patents Nos. 652,326, and 693,666, respectively on embroidery machines were issued .1.5 to. me.

plie-ation, Serial No. 288,208, for a p'atent on an embroidery machine. These' patents and the said application disclose my autcmatic embroidery machine, andvarious iinprovements in connection with the same.

The object of my present invention is. to make various other improvements vin this machine, and the 'invention consist-sof these various improvements, ywhich will'be disclosed in connection with the specification,

' and specifically set forth in the claims.`

Referring now to4 the drawings: Figure 1 is a iront elevation, and Fig. 2 a rear elevation of the machine, and Fig. 3 is a top plan 3c view, the arm being omitted to showthe relation of parts under the same. Fig. efis a November 20, 1905, l iiled an ap top plan view oi the-work carrier and car-. riage, and the mechanism carried by thev same.` Fig. 5 is an enlarged detached top plan view ot tneinechanism for revolving the work carrier; Fig. 6 is a vertical cross sectional view taken on lines 6-6, Fig. 5,

Fig. 17 is a detached top plan view oi the compound mechanism for reciprocating the work carrier, and Fig. 18 is a detail sectional view taken on lines 18-#18 of Fig. 17. Fig. 19 is a bottom 60 plan VView of the. bridge of the compound mechanism showing the part carried'by the saine, and Fig. 20 is a top plan view of the parts under the bridge that drivespthe parts carried by the'bridge. Figs. 21 to 25 incluc5 sive are details showing the construction of the intermediate slide. and connecting devices through which the ymovei'nent of the compound mechanism is transmitted to the workcarricr carriage. Fig. 26 is a top plan 7c view oi' a part of the driving mechanism that operates the mechanism carried by the work carrier carriage, and Fig. 27 is a sectional view 'of the saine on lines 2T- 27, Fig. 26, looking in the directionof the arrow in said `figure. Figs. 28 and 29 are sectional details showing the construction of the work carrier, and the manner in which it is carried by the work carrier carriage. Fig'. I3() is an enlarged'sectional detail on lines SOBO, Fig. 80 1. Fig. 31 shows the end of the needle-bar connection on the needle-bar operating lever below the ulcrum of the same, and Fig. 32 shows the end of said connection above the fulcruinof said lever.V Figs. 33 and 34 are 85. diagrammatic views K illustrating a detail. Figs. 35 to 40 illustrate the double presser iootl and the structure and manner oi operating the same. Fig. e1 is a diagrammatic view y showing the interlocking of the stitches along 90 the edge of `the design. Fig. 42 is a, front side view of a part of the machine, .the base being in section to expose the looper mechanism. Fig. e3 is a viewshowing'the manner in which the power is transmitted from the, driving shaft to the needle positioning inechanisnr Fig. 4e illustrates' the means -oi adjustment to increase and decrease the speed of rotationof the work carrier. Fig. y 45 is a detail in connection with the friction 100 device. Fig. e6 is a detail in connection with the transmission of the power from the driving shaft/to the work moving mechanism.

In the drawings, l indicates the arm ofthe machine, 2 the base, 3 the upper or driving 105 shat, 4 the lower or looper shaft, and 5 the table on which the head and the work mov-H ing mechanism is mounted. y, The lower shaft 4 is driven, by means not shown, from the movement of the driving il() shaft, and revolves in unison with saidoriv ing shaft. in practice, I prefer to drive thevbroidery or ornamental stitch machine.

lower shaft by means of a chain, as shown in my copending applica-tien, Serial. No. 17 8,629, ornamental stitch machine, tiled October 26, i903.

To the forward'end of the shaft 4 is secured a gear wheel 6 which/is in engagement with a gear wheel 7, the latter being one half the diameter of the former. The gear wheel 7 is secured to the under side of a looper 8 that is carried by the upper end of a shortx vertical shaft 9. On the looper 8, is formed a beak 10 that is adapted to engage the needle thread loop, and in combination with au ausili ary hook 11, pass the same around a bobbin case 'i2 that is carried by the hook 8. (Fig. 42.)` This looper mechanism is the same shown and described in my cepending application, Serial No. 277,774, filed September Q, 1905, looper mechanism for sewing machines. 1 i

@n the shaft 4 is' secured a bebbin contreller cam 13, which engages with the outer end ef a leverf14 that carries a bobbin lcontrcller 15., that is adapted to engage in a suit.- able manner the bobbin and thereby control the same. This bobbin controller mechanism is the same as shown and described in my copending application, Serial No.288,208, iiled November 20, 1905, automatic empractice, when the machine is to berun at a very high rate of speed, the bobbin controller shown and described in my copending application, Serial' No. 154,457, filed April 27, 1963, is used,

in suitable bearings in the forward end of the arm ef the machine isjournaled to reciprocateand oscillate, a needle-bar 16, that carries a needle-helder 17,*in which is secured a needle 18. The axis of the needlebar is coincident with the axis of thehook or locper shaft 9. @n a suitable bearing 19 that .is secured to the top of the forward' end of the machine, is pivoted a lever 2() which has a downwardly. extending part 21,A in which. is adapted to reciprocate a red 22, that is carried by the outer end of an arm 23. rhe arm 23 is secured to the needle-bar by means not shown, and the needle-bar is reciprocated by means, not shown, o erated by the'forward end of the driving s aft of the machine.

rihe parts in connection with the needlebar which reciprocate it and permit it to be oscillated are fully shown and described in my ccpending application, filed November, 20, 1905, Serial No. 288,208.

it will'now be understood in connection with the needle-bar and its operati-ng par-ts, that when the arm 21 is oscillated, the needlebar is .moved laterally, and through this movement, the needle is moved late-rally. The axis of the needle-bar being coincident ywith the axis of the-hook, it is of course, un-

derstood that the needle mcves laterally in a ,ece

beak l() of the hooki' The means by which the needle is moved laterally, will now be described. Y

On the driving shaft of the machine, is secured agear wheel 24, which en ages and 0perates a gear Wheel 25, the hu of which is journaled in a bushing 26.

cured to the rear side 'of the armvo'f the machi'nev-lo the end of the hub of said gear 25, is secured a`disk 28, that carries a crank pin 29, o n which-is formed reduced portions 30 and 31. To the reduced portion 31 is secured a part 32 on which is formed a crank or Wrist-pin 33.

One end of a pitrhan 84 is pivoted on the reduced portion 30 of the crank pin 29, and

the outer end of an arm 85. The arm is sewhich latter is journaled in a bracket 37 that is secured to the top of the arm `of the machine. To the forward end of said shaft, is lsecured an arm 3S, (Fig. 1), in the face `of of the shaft 36. in said wayis adjustably secured one end of a link 4f), that at its other end is pivoted on a stud screw 41,. The stud screw has a seat in the outer end .of a pawl lever 42, that" is pivoted on a shaft 43, and the shaft is journaled in the bracket 37. To

Y\the forward endv of said shaft,.is 'secured a ritel-'ret1wheel.44, and on the-bearing er screw 41., is pivoted a p'awl 45 that is'in engagement with said ratchet wheel. The lower end o f a link 46 is adjustably secured in a way formed in a projectionthat is located on the side ofthe ratchet 'wheel 44. This Way runs over the axis cf the ratchet wheel shaft 4'3, so the end of the link 46 may be adjusted over the axis of said wheel, and the moveratchet wheel thereby arrested. The upper end of the link is pivoted on abear ing 47 that projects horizontally from a part 48,. which latter is adapted to slide on a post (Fig. 30.)

wheel 44 maybe rotated by the parts that reciprocated,

On Ithe forward end of a short shaft 50, which is. journaled in the bracket 37, is secured one 'end of a lever l51. On the rear a part 56 on which is formed a boss 57. To the face of the boss issecured, by means of the other end df said pitman is connected tof cured to the rear end of a shaft 36, (Fig. 2),

'L will be now understood that the ratchet which is'journaled the stem 53 of a shoe 54,

55, carried by the driving shaft of the Inascrews 58, a part'l and Ythe upper end of anv path that is concentric/with the path of the rihe said bushing 1s secured to a plate .2.7.,-that in turn is sewhich is a way 39, that extends over the axis v ment of the link from the movement of the 49, and-the post has a seat inthe bracket 37 have been described, and that when thesaid` ratchet Wheel is rotated, vthe part Li8,-rnayln-i"
